What it can do

list_rules_taking_effectWhat lands on me, and when? Lists already-published US federal final rules whose effective date falls between two dates, soonest first, optionally from one agency.

Common questions
Is US federal rules taking effect safe?
It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 2 months ago, and the latest version (1.0.0) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

referencesource-mcp
MCP server for [referencesource.org](https://referencesource.org) — small, verified reference datasets where every record carries its source URL and a verbatim quote from that page, so any value an assistant gives you can be checked, not just believed.
285 datasets, 110,000+ records: regulatory thresholds and deadlines, version compatibility, standards supersessions, certification registers, inspection requirements, and more. Each dataset states its coverage and its last-verified date.
Tools
| tool | what it does |
|---|---|
list_datasets | every dataset with record counts and descriptions |
search_records | search within a dataset; each hit returns the value plus its source URL and verbatim source quote |
get_record | one record by id, full provenance included |
verify_quote | give it a dataset slug and a value you already hold (record id and field optional) — it checks that claim against our published records and says whether it matches |
verify_quote is the unusual one: assistants invent plausible-but-wrong values roughly 19% of the time in our own measurements, and this is the check. Four verdicts come back:
| verdict | what it means |
|---|---|
matches_record | the claim equals the stored value; the match type is named (exact, case-insensitive, normalised) |
matches_quote | not a stored value, but it does appear in the record's source quote |
differs | the record holds a different value — both are returned, with the source |
not_found | no record in that dataset carries it |
Where a record is found, the answer carries the stored value, the record URL, the source URL and the verbatim quote, so the claim can be traced upstream — plus an attestation saying plainly that the verdict is about what our source states, not about what is true in the world. Asking whether the 2026 conforming loan limit for Autauga County, Alabama is $806,500 returns differs, stored value $832,750, quoting the FHFA row it came from.
Scope, stated so nobody overclaims: these tools search referencesource.org's own published records. They do not fetch arbitrary URLs and cannot check a claim against a page we have not harvested. not_found means "not in this dataset", never "false".
Setup
Claude Desktop — add to claude_desktop_config.json:
{"mcpServers": { "referencesource": { "command": "npx", "args": ["-y", "referencesource-mcp"] } } }
Cursor / other stdio MCP clients — same idea: command npx, args ["-y", "referencesource-mcp"].
Clients that support remote servers directly don't need this package at all — point them at the streamable-HTTP endpoint: https://referencesource.org/mcp.
Notes
- Zero dependencies; Node 18+. The package is a thin stdio→HTTPS bridge to the stateless server at
referencesource.org/mcp. - No accounts, no keys, no tracking beyond standard server request logs (see referencesource.org/privacy).
- Data is free to read on the site in HTML, Markdown, and JSON; this package just makes it callable mid-conversation.

The data behind it
- Site: https://referencesource.org — canonical, re-verified on a schedule
- Bulk data: https://github.com/joelp22-maker/referencesource-data
- Archived snapshot with a DOI: 10.5281/zenodo.22115966
- Hugging Face: https://huggingface.co/datasets/referencesource
Every record carries source (the page the value was read from) and source_quote (the verbatim line on that page which states it), so any answer this server returns can be checked against its source. verify_quote runs that check against a value you already hold: it tells you whether our record agrees, and hands back the source and quote either way.
